Embodiment 1

[0033] See figure 1 , figure 1 It is a schematic structural diagram of the liquid weighing device provided in Example 1 of the present invention. The liquid weighing device in this embodiment includes a tank body 1, a connecting pipe, a liquid scale 2 and a liquid storage tank 3;

[0034] The tank body 1 is a piston cylinder with a uniform cross-section. The inside of the tank body 1 is provided with a fluid replacement chamber 101 and a piston 103 that slides and fits in the tank body and is used to change the volume of the fluid replacement chamber. The lower part of the tank body 1 is designed as a fluid replacement chamber 101. The cavity 101 can also be arranged on the upper part of the tank body 1 .

[0035] The connecting pipe includes a first weighing tube 121 and a first liquid storage tube 131. The liquid replacement chamber 101 communicates with the liquid scale 2 through the first weighing tube 121, and the liquid replacement chamber 101 also communicates with th...

Embodiment 2

[0046] See figure 2 , figure 2 Schematic diagram of the structure of the liquid weighing device provided by Embodiment 2 of the present invention. The liquid weighing device provided in Embodiment 2 of the present invention includes a tank body 1, a connecting pipe, a liquid scale 2, and a liquid storage tank 3; the inside of the tank body 1 is provided with a liquid replenishment chamber 101, which is slidably fitted in the liquid replenishment chamber and used to change the liquid replenishment chamber. The piston 103 of the cavity volume; the connecting pipe includes the first weighing tube 121 and the first liquid storage pipe 131, and some other connecting pipes have been added; the difference between the liquid weighing device in this embodiment and the embodiment 1 is that, The second weighing tube 122, the second liquid storage tube 132 and the buckle cavity 102 are added (note that the buckle cavity 102 at this time is the liquid replacement cavity 101, and the two...

Embodiment 3

[0051] See image 3 , the liquid weighing device in this embodiment includes a tank body 1, a piston, a connecting pipe and a vent pipe; the inside of the tank body 1 is provided with a liquid replenishment chamber 101 and a piston 103 that slides and fits in the liquid replenishment chamber and is used to change the volume of the liquid replenishment chamber The connecting pipe includes the first weighing tube 121 and the first liquid storage tube 131, and it also increases some technical structures on the basis of the scheme of embodiment 1; for example: it increases the second weighing tube 122 and the second storage tube The liquid pipe 132, the air pipe 104, and the weighing cavity 102; the air pipe is connected to the weighing chamber; the air pipe is provided with a valve (namely, the air pipe valve 104a). in image 3 The medium replenishment chamber 101 and the weighing chamber 102 are two chambers on both sides of the piston 103 .

Abstract

The invention relates to the field of metering devices, and in particular relates to a liquid weighing device. The liquid weighing device comprises a tank, connecting pipes, a liquid scale and a liquid storage tank; a liquid supply cavity and a piston are arranged in the tank; the piston is used for changing the volume of the liquid supply cavity; the connecting pipes include a first weighing pipeand a first liquid storage pipe; the liquid supply cavity is communicated with the liquid scale through the first weighing pipe; furthermore, the liquid supply cavity is also communicated with the lower part of the liquid storage tank through the first liquid storage pipe; and valves are arranged on the first weighing pipe and the first liquid storage pipe. According to the liquid weighing devicein the invention, the tank is arranged between the liquid storage tank and the liquid scale; the weighing precision is improved; and thus, the problem that the metering error in a large range is relatively high in a liquid weighing process in the prior art can be solved.

Description

technical field [0001] The invention relates to the field of metering devices, in particular to a liquid weighing device. Background technique [0002] Concrete is one of the most important civil engineering materials in contemporary times. It is composed of cementitious materials, granular aggregates (also known as aggregates), water, and additives and admixtures added when necessary, prepared in a certain proportion, uniformly stirred, densely formed, cured and hardened. artificial stone. Concrete has abundant raw materials, low price, and simple production process. At the same time, concrete also has the characteristics of high compressive strength, good durability, and a wide range of strength grades. These characteristics make the use of concrete very wide. [0003] Concrete formulations contain various liquid raw materials, such as water and external agents. The accuracy of weighing the liquid raw material determines the quality of the concrete. Limited by the con...
